MiniCPAN: When and How Much

[ #35525 ]

I want to see how much of the stuff in my MiniCPAN was uploaded when:

$ perl dir_sizes.pl /MINICPAN

I'm working on doing the same thing for BackPAN and CPAN, but have a couple of data collection issues to work out. I'm also working on doing the same thing for numbers of authors each month, numbers of new authors each month, and so on. When I get this worked out I'll release the code, but it's relly just File::Find and some path processing and counting.

  • I'm not confinced this would make a good surface plot. Despite the way it's presented as a two-dimensional histogram, it's really only one time line and the amount of data. So what's wrong with a simple 2D plot (except the following one is ugly)? http://steffen-mueller.net/tmp/cpanuploads.png [steffen-mueller.net]
    • Well, I also want to see yearly cycles, and look at slices like "December". People can make all sorts of graphs though.

      Note that your graph is really "Age of distros in MiniCPAN", not CPAN Uploads. The only things there are the lastest ditros, which is why January 2008 has such a big spike. :)
      • Yeah; to me it's really cool that 8.2% of CPAN by size has been released or revised in the last month. And 38.8% of it within the last year. Most modules people are running are something that is new and fairly recently looked at, especially if it has a good test suite. :)

        Of course, I'm really curious what the gigantic distribution is in September 1997 that hasn't been touched in the last ten years.

        • Don't get into the numbers too quickly. This is just MiniCPAN, so that excludes Perl distributions and so on. CPAN has a lot more current stuff than what shows up in MiniCPAN. It's not something to measure to tenths of a percent.
